Abstract
We introduce a new mechanism for evolutionary discontinuities in ecosystems and discuss the relation with punctuated equilibria, stasis and gradualism. We conclude that these phenomena are natural consequences of a nonlinear dynamic approach to evolutionary stability. In addition we discuss some insights into speciation and the role of phenotype constraints in determining the validity of the Red Queen hypothesis.Keywords
